With the code below (adapted from an old question here) I create a list of all folders and subfolders within a give path (using the command genpath and strtok). Using strfind I then select only those folders that contain a given keyword. However, strfind only allows inclusive search, but how can I make e.g. condition 3 such that it only selects the paths that DONT contain the keyword?

listOfFolderNames = {};
allfolders=genpath('D:\test\');
while true
[singleSubFolder, allfolders] = strtok(allfolders, ';');
if isempty(singleSubFolder), break; end
listOfFolderNames = [listOfFolderNames singleSubFolder];
end
indices=strfind(listOfFolderNames,'word a);   % <-- filter condition 1
Index = find(not(cellfun('isempty', indices)));
foldersa=listOfFolderNames(Index);
indices2=strfind(foldersa,'word b');   % <-- filter condition 2
Index2 = find(not(cellfun('isempty', indices2)));
foldersb=foldersa(Index2);
indices3=strfind(foldersb,'word c');   % <-- filter condition 3. How to make this eclusive??
Index3 = find(not(cellfun('isempty', indices3)));
foldersfinal=foldersb(Index3);
